This route has two ferry boat crossings. One is free the other is paid. Last time I used the ferry it was $2 or $3 round trip I think.
In Grafton there is a great place to eat called the Finn Inn. It has HUGE aquariums with giant fish and turtles in them. They serve seafood steaks, burgers. They also have a fantastic catfish I think they call it buffalo fish or something and it is HUGE if you order that be prepared to eat alot!
